Cool season turfgrasses have necessary functions in the landscape, but are associated with excessive water use. Cities have begun to reuse water for outdoor purposes as a response to a shrinking water supply, this ‘effluent’ water has higher salt content. This high salt content puts turfgrasses under increased stress. The focus of our research is to investigate the involvement of two genes in salt tolerance among turfgrass species: an H-type thioredoxin (Trx) that reduces oxidative damage within salt stressed cells, and a vacuolar (v-type) ATPase subunit that transports +H ions across the vacuole membrane to maintain osmotic potential under higher salt conditions. In this experiment we test if the gene expression of these two genes is higher in tolerant turf species and cultivars vs. susceptible species and cultivars under salt stress.
